* Provide an optimized implementation of ffs(3) in the kernel onnaddy2020-06-103-0/+47

* If we pass a packet length larger than 2^16, we should panic() insteadpatrick2020-05-191-5/+3
| | | | | | | | | | of returning -1. With a return type of u_int16_t, -1 is not different to a valid checksum. For incoming packets, the header lengths don't exceed that size anyway, but for outgoing packets it's better to see if our bootloader crafts a broken one. Discussed with gerhard@ ok deraadt@ procter@
* Sync in_cksum.c to the same version ospfd has. This fixes problemspatrick2020-05-182-30/+29
| | | | | | | | | | with odd packet lengths, which can happen when using TFTP to load a file with an odd length. ospfd actually took dvmrpd's version in 2006 to fix the same issue, and both daemons implementations are the same. For the bootloader we keep the consts from the previous version and replace the fatal with a print and return. ok deraadt@
* Add __lshrti3 to libkern and use it on sparc64jca2020-04-021-0/+71
| | | | | With this it's possible to build the kernel using clang. Discussed with claudio@, ok deraadt@

* Remove non-__STDC__ assert macros from <lib/libkern/libkern.h>.visa2020-02-261-22/+1
| | | | | | | | The macros are defined in a part of the header where a C compiler is required. In addition, the macros expand to C code, so it looks unnecessary to define the asserts with traditional cpp in mind. OK cheloha@, mpi@

* Reduce BOOTRANDOM_MAX to 256. naddy pointed out there's no point havingderaadt2019-11-011-2/+2
| | | | | it larger than RC4STATE. A long discussion ensued. In conclusion all entropy inputs are either satisfactory enough, or just as shitty at 512.
* Use arc4 to bit-spread the 512-byte random buffer over the .openbsd.randomdataderaadt2019-10-291-9/+8
| | | | | | | | | section, which has grown a fair bit with the introduction of retguard. Mortimer discovered the repeated 512-byte sequence as retguard keys, and this resolves the issue. (Chacha does not fit on the media, so 1.5K early drop RC4 is hopefully sufficient in our KARL link universe) Version crank the bootblocks. sysupgrade -s will install new bootblocks. ok djm mortimer

* In the bootblocks, after discovering and opening /bsd.upgrade, fchmod -xderaadt2019-08-036-6/+176
| | | | | | | | | | | | | | | | so the file cannot be re-executed upon the next boot. This provides a stronger one-shot-upgrade model than the upgrade script's rm /bsd.upgrade. Now various forms of upgrade failure will reboot into /bsd, which is probably more recoverable. Performing fchmod -x depends on (1) use of MI boot.c (not alpha/macppc/sparc64/sgi/octeon) and (2) "can write blocks" functionality in the IO layer. Most architectures have this support now. Two diagnostics "fchmod a-x %s: failed" and "/bsd.upgrade is not u+x" will remain in the tree while refinements happen for some of the laggard architectures. based upon a discussion florian tested in snapshots for more than a week without any complaints
* Fix warnings when building zlib with ZLIB_CONST definedjca2019-06-013-8/+8

* Retry on incorrect passphrase for softraid crypto boot.jsing2018-08-102-72/+122
| | | | | | | | | | | | | | | | | | | Historically, the softraid crypto support in the boot loaders has only given one attempt to provide the correct passphrase. There were a few reasons for this, including the fact that pkcs5_pbkdf2() allows an empty passphrase and that returning EPERM allowed for another attempt. With the event of KARL and the need for bsd.booted with hibernate resumption, this becomes much more of an issue - if you get the passphrase wrong you fail to resume. There are also other situations like using /etc/boot.conf to switch serial console, but an incorrect passphrase results in the config not being read. Also, bcrypt_pbkdf() does not permit empty passphrases. This reworks the softraid crypto support in the boot loaders so that it loops requesting a valid passphrase until one is provided, or an empty passphrase is entered (at which point it will abort). ok mortimer@ tb@

* Stop converting UDP and IP header values from network endianness to hostpatrick2018-03-311-10/+7
| | | | | | | | | | endianness for convenience reasons. Especially in code pathes like TFTP where the source port is read from the received UDP packet and used as destination port in a new UDP packet this can be very harmful. Luckily this issue has had no effect on our architectures since they never use any of the code paths that could be harmful. ok visa@
